Happy Halloween!
Today's dispatch asks - How do you feel after eating candy?
Most students answered they feel hyper and energetic, that they feel like eating more, and if they eat too much they feel sick.
Then we began taking Cornelle Notes for Assignment 47 - Mitochondria and Chloroplasts.
The notes discussed how sugar is used in the cell - how it is broken down from glucose to energy in the process called cellular respiration. This starts in the cytoplasm in the process of glycolysis, and finishes in the mitochondria. Glucose is broken down into ATP (cell energy) and molecules of carbon dioxide and water.
Then we discussed photosynthesis, and how plants are able to create sugar with their chloroplasts, which contain chlorophyll- a pigment which can absorb sunlight. The glucose they create can then be stored as other more complex carbohydrates - such as sucrose, starch, and cellulose. Cellulose is the building block of cell walls and is not digestible by humans. You may commonly hear it referred to as "fiber."
Finally students took a quiz on cell organelles, and had a few minutes of free time to see each others costumes and eat some candy (today only!)
